Professor, your turtle!

Lao Xu called up a previous test question on the ppt:

"Among the following descriptions about the excretory system of reptiles, which one is correct: (single choice)

A. The reptile kidney belongs to the metanephros systemically, and does not pass through the pronephros and mesonephros during the embryonic period

B. The basic structure of the kidneys of reptiles is not substantially different from that of amphibians, but the number of nephrons is greatly increased

C. The urine produced by the kidneys of most reptiles is sent to the bladder by the ureter for storage, and is reabsorbed and then excreted by the urethra

D. The nitrogenous waste excreted by most reptiles is mainly urea"

[Note: Quoted from "2015 National Biology League Test Questions for Middle School Students"]

Ji Fan: "..."

Ji Fan: "..."

As a Turtle Star, he couldn't understand this question very well.But what is this vague sense of shame?

Old Xu raised his voice and asked, "Does anyone know?"

There was no sound in the classroom, but a few students in the front row were whispering to each other, but they couldn't argue with each other.

Old Xu was a little disappointed: "Well, this question involves a lot of knowledge. Although reptiles are not taken in the college entrance examination, this is a popular self-enrollment."

"If no one raises their hand, we will announce the answer..."

Ji Fan clenched his fists: If I miss this question, I don't know when I will have such a good opportunity again.

There was a battle between heaven and man in his mind.Fu Mingyuan's embarrassing frown seemed to flash before his eyes, and he didn't know where the impulse came from, he actually gritted his teeth and raised his hand.

"?" Old Xu was slightly surprised.

Ji Fan resisted not letting go of his hand, the whispers around him became louder, and even Xu Haifan was surprised, as if he hadn't expected that he would take the initiative to speak.

Suddenly, everyone's eyes turned to the other side. Ji Fan took a look and saw the other hand raised high at the other end of the classroom.The man turned around with a provocative look - it turned out to be Zhao An.

Wow, there is a good show to watch.Everyone's eyes swiveled between the two, as if expecting to see crackling sparks.

But Zhao An just snorted coldly in disdain, and turned to the front again.

"Then..." Old Xu moved a little bit, thinking of Ji Fan who hadn't raised his hand for thousands of years, stood up and answered.

"Teacher, I raised my hand first!" Zhao An argued first.Just kidding, how could she let that kid show off.

"..." Old Xu said helplessly, "That's fine, you can talk about it first."

Zhao An smiled triumphantly, and stood up confidently: "I should choose C." After speaking, she explained, "Reptiles are indeed progressive metanephros, but embryonic development has to go through the process of promesonephros, so A is wrong. B If the reptiles have double kidneys, they have not 'greatly increased'. D is also wrong, excreting nitrogen is not urea, but uric acid."

What she said was well-founded and logical, which made Lao Xu nod repeatedly.

Noticing the envious and admiring eyes of the students around him, Zhao An's heart swelled up like a balloon, and he sat back with satisfaction.

Ji Fan frowned slightly. Most of what Zhao An said was fine, but it seemed to be different from his choice...

"Well, a few error-prone points are explained well," Old Xu turned his head, "Ji Fan, is there anything else to add?"

want to say?Ji Fan opened his mouth, and there were questioning eyes all around him, which made him flinch involuntarily.

Maybe Zhao An is right, the one who made a mistake...was him?

Ji Fan's self-confidence, which was not strong at all, became weaker and weaker, and his opened mouth closed again.Old Xu noticed his strangeness, his eyes lit up slightly, and he encouraged him: "Just talk about it, we are discussing, it doesn't matter if we are wrong."

Ji Fan stood up bravely and said, "I chose... B." There was an uproar, not only because Ji Fan raised his hand to answer the question, but also because he dared to overthrow the answer that sounded correct.

The matter has come to this point, so I have to continue talking, Ji Fan muttered: "C seems to be..."

Old Xu showed interest: "What's wrong with C?"

"I remember that amphibian bladders don't seem to be, no," Ji Fan paused, blushing inexplicably, and stumbled, "It doesn't include the ureter."

If he recalls correctly, most reptiles only store their urine in the protuberance of the cloaca, and then make their way to the bladder, without passing through the ureters—the same goes for turtles.

Ji Fan's face turned even redder: Don't ask him how he knew!He really doesn't want to remember.

In front of the podium, Lao Xu's expression suddenly softened, and he smiled: "Okay, very good! Yes, this is also a trap question. It seems that the focus of option C is 'reabsorption' rather than 'ureter', but in fact, it is It’s easy to make the wrong choice.”

Zhao An's face turned pale, and he pursed his lips in silence.The classmates who were standing on her side all turned their heads and looked at Ji Fan in surprise—are you kidding, is that Ji Fan right?

Ji Fan, who was at the end of the monthly exam, actually answered questions that Zhao An didn't even understand?This is dreaming!

"Damn, did he read the answer?"

"Old Xu has always created questions by himself, how could he have read them?"

"Then how did he know? Didn't the reptile textbook mention it at all?"

"The competition team has something to say..."

"He's not in the biology competition group!"

"Don't be sour, please. After all, people are doing homework every day. What are you doing?"

"..."

Old Xu reassured: "Student Zhao An is right. Option B is indeed not rigorous enough. But in this case, if you choose one of the two, the correct answer should be B."

Zhao An didn't listen to this reassurance at all, she stared at her homework book, she just felt that her face was lost, and the slightest disturbance nearby seemed to be that they were talking about her being inferior to Ji Fan.

Zhao An clenched his fists and clenched his teeth, he could almost taste a trace of blood.

——Too annoying, that man!Isn't it good to hide in the shadows honestly? Why, why do you still come to block her way?

She was in a turmoil, thinking wildly: "Look, he must be laughing at her, just like those people around! They, they all want to climb on top of her..."

Zhao An was too sensitive, in fact, Ji Fan didn't even look at her.Hearing the sound effect of the task being completed, he was greatly relieved and sat back on the stool.On the blackboard, Old Xu has already started to explain the next knowledge point.

Except for Zhao An's small group, the other students may look at him with surprise, but most of them are kind.

Most of the young students in the ivory tower are pure-minded. Most of them may not intentionally bully anyone, but more or less, they all have a herd mentality.

Once a black sheep appears in the flock, it is easy to become the target of unconscious crowding out.

Zhao An has been trying to isolate Ji Fan from the flock.

However, Ji Fan's recent performance seemed to give them the opposite signal - the original clumsy black sheep seemed to have tried hard to catch up with the main force.

The generous flock deserves him.So, they tried to show kindness to Ji Fan again.

Ji Fan felt a little awkward.He remembered reading a story that hurting others was like driving a nail into the wall. Even if the nail was pulled out, mottled holes had already been left on the wall.

The ridicule of the past seems to be still in my ears.After being isolated for so long, the sudden friendliness made him avoid it.

Ji Fan's not-so-enthusiastic attitude didn't surprise others.After all, in their impression, this guy has always been alienated and indifferent.

There were quite a few girls in the class who hated Zhao An's arrogant attitude in private, so they argued for him at this moment: "What do you know, it's called coldness."

The interpersonal relationship on campus is like a complicated net. Ji Fan originally just stood outside and watched silently.

Comparing the two, Ji Fan thinks Mr. Fu in the pet egg is extremely cute.

……

In the turtle shell space, Ji Fan was sorting out the inventory of his backpack when he suddenly found that there was an extra food reward in the corner.

【Shrimp Sashimi X1】

[Limited-time props, with a shelf life of 7 days. 】

Ji Fan: "..." The so-called endangered is an excuse, isn't it, the system asked him to raise shrimps just to guard himself? ?

The light screen twisted for a moment, and after a while, a commentary reluctantly appeared underneath.

It turns out that in the process of breeding krill, if the population density is too high, the shrimp will eat each other, or even stop breeding, which is quite unfavorable for the task.

The breeding speed in the incubator is much faster than in the natural environment. It used to take at least a month for deep-sea shrimp eggs to break through, to float up, and then to grow. Now it only takes a few days to complete.

In this way, isn't the density exceeding the standard?

So the system automatically removed some large krill that were not in the breeding season and used them as task rewards.

It's really waste.Ji Fan's lips twitched.

The troublesome question is, what to do with this shrimp sashimi?

Curry solitaire, canned rice, etc., can be said to be things that originally existed in the house, but if a fresh shrimp appeared out of thin air, I'm afraid it couldn't be explained.

Ji Fan had a headache, thought about it, and finally decided to pay attention, planning to take out the sashimi while the other party fell asleep tonight, and eat it secretly.

——Although I feel sorry for Mr. Fu eating alone, there is no other way.He couldn't help laughing when he thought of Fu Mingyuan's depressed expression on eating canned food.

In order to save enough Qinxuedou to exchange for diesel, Ji Fan raised his hand twice today, and the accumulated reward value reached more than 600 at one time.

However, the newly opened column in the mall only has a column of 500 beans, and it seems that 1000 beans are needed for the next advancement.

Ji Fan sighed, that's right, how can there be so many benefits?This system is like a krypton gold game. Once the way to obtain beans becomes easier, the price of high-end goods will also increase, and in the end players will still be poor.

The developer must be a big profiteer!He cursed silently, and suddenly sneezed uncontrollably.

Have a cold?Ji Fan shook his head, but he didn't notice anything unusual, so he stopped paying attention to this issue and carefully looked at the 500-bean product.

All in all, you get what you pay for.After seeing it clearly, Ji Fan was refreshed, and immediately stopped complaining about their expensiveness.

"A pot of shallots, planting garlic, lettuce seeds, ginger seeds..." The food bar is no longer consumables, but green plants and condiments that can be cultivated repeatedly.

Lettuce, shallots, garlic, etc. have a very short growth cycle, which is very suitable as a vegetable substitute in times of scarcity - as long as you buy a pot, you will never have to worry about running out of food in the future!Really good value for money.

Similarly, the energy zone is also very attractive - 500 beans can be exchanged for ten solar panels!Compared with diesel, although the production efficiency is not high, it is superior in quantity and can be used repeatedly.

In addition, the entertainment section finally appeared.This time the sale is "two-player board games", including two-player board games, checkers, chess, go, chess and so on.

Different from playing cards, the system has a separate note, and you can interact with "Tama" through a two-player board game to increase your bond!Although I don't know how to operate it, it seems that as long as I have it, I can play with Fu Mingyuan without entering the space.

With so many interesting products, Ji Fan was confused for a while, which one should I change first?
